Settle delay and other timings, three-mode drives
In all likelyhood, the stock values work. I have never seen a drive actually need more than a few milliseconds for settling and since the index pulse is typically waited on, you are pretty much guaranteed to have a ton of time sitting idle. You can set the defaults to whatever you like.

I am not sure what a 3-mode drive is. Yes, SCP can control pin 2. That is the density, and you can read/set that using command 0x8C.

If you are planning on writing your own control software you might want to look at existing examples, like Keir Fraser's disk utilities or a8rawconv. Both of these have code for stepping, reading, writing, etc. as well as handling the .scp image file format.
